Sand mastic in Woodway
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Typical jobs include old sand mastic that has cracked, crumbled or fallen out and gaps between timber frames and stone or brick, on tenement windows, period & listed homes and sash and case windows.
Mastic can only go onto a dry, clean joint, so window work in Woodway is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee, large or small.

Keeping the joints in good condition
Aftercare is simple:
- Inspect the joints round the windows every year or so
- Take care around the mastic when scraping paint
- Leave the new mastic unpainted
- Check with your local planning authority if your home is listed
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
The process
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Woodway, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sand mastic in Woodway: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Brightwell Manor (about 5 miles north-east) are a reminder that the area around Woodway has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Cholsey station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like Blewbury Endowed Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Can you do sand mastic in Woodway?
Yes. Our work covers London and the South East, and Woodway is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.

How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours per window, depending on the condition of the joints. We’ll tell you when we quote.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Do I need permission for sand mastic on a listed building?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish but the decision is theirs.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Leave it or put it right?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Around Woodway, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.
What you get with us
- Old sealant always removed completely
- Domestic, commercial and hotel work
- Arbo and Everbuild products
- One-year guarantee on every job

When to call us in Woodway
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Look out for these signs:
- Gaps between timber frames and stone or brick
- Gaps round a timber door in stone or brick
- Tired mastic found when preparing windows for paint
- A silicone bead on a sash window that spoils the look
Homes close to Church of St Michael include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
